I recently (last month) went to my general Dr. for unexplained headaches (never suffered before), and dizzy spells. I am 32 years old. Being a military spouse, we move a lot,and I was told that it sounds like allergies, compliments of our new location (20 away from Chicago IL). A CT scan was ordered to check for a clogged sinus cavity, I was put on zyrtec-D and sent home. My CT scan showed no sinus blockage, but indicated a possible Chiari 1 malformation. My Dr. blew it off, said that I was probably born with it, that it only shows symptoms in childhood, so I would never have any problems. After doing my own research and finding this site, I am for sure WAY more concerned. I have made another Dr. appt. and am going to insist on an MRI for definative diagnoses, and a referral to a Nuerologist that specializes in my situation. The zyrtec-D did take the headaches away. But the dizzyness is still there, and occasionally I get numbness in my upper arms. I currently have 3 children all c-sections. Before my CT findings, my husband and I were talking about one last baby to complete our family. I want the MRI and an appt. with a specialist before I get pregnant. But I was just wondering if getting pregnant would make symptoms worse? I am also having 2nd thoughts now that I know it can be passed on. Do you have any advice for me?
